How to Check the HandsFreeLink System Condition

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Check the vehicle battery condition first (see BATTERY TEST ).
The self-diagnostic function can only be initiated while the HFL is in its idle state.
The self-diagnostic function starts after you press and hold the BACK button on the voice control switch for 5 seconds, and ends if the HandsFreeLink control unit returns to its idle state.

Turn the ignition switch to ON (II).
Press and hold the BACK button (A) for more than 5 seconds.

When the HFL system enters the self-diagnostic function, the following will occurs:
- Without navigation: If the system has not completed testing for HFL DTCs, HandsFreeLink Self Diagnosis in progress... is displayed on the audio display.
- If the HFL is OK, and there are no HFL DTCs, the HFL system says, "The HFT is OK."
- If there are any HFL DTCs stored, the HFL system says, "The HFT is NG."
